What you are describing is an array of arrays (AoA), which is pretty much a 2D array. Why do you wish to avoid what may be the best tool? Of course if the names field is unique (ie, you never have duplicates) you could also represent your datastructure as a hash of arrays (HoA).

In Perl, a 2D array is really just a narrow subset of what is broadly described by the word "datastructure". And you can read all about manipulating complex datastructures in the perldocs (POD). perllol = "Perl lists of lists", perldsc = "Perl datastructure cookbook", and of course perlreftut = "Perl references tutorial". After reading through those documents (consider them your homework assignment -- they'll take you an hour or so) you'll be much better equipped to answer the very questions you're asking here.
